The nonsense that this whole 'who makes Olympus' sensors' argument is based on is that Panasonic wouldn't 'give' Olympus their best sensors. More likely, Olympus was unprepared to put the investment into sourcing better sensors, thinking it could go on with the old ones. Now, under a new management, it is putting some investment in and has sourced at least two leading edge sensors from different manufacturers.

Superbly argued! The money was probably more needed in the cosmetics venture.

However you are pouring icy water over people's romanticized notion of this 'm43 relationship' in terms of a familial rather than business context which has allowed them to cry like a wronged spouse. Cruel

We can really only speculate as to what happened back in the day. Another possibility is that Panasonic simply couldn't produce the larger sensors in sufficient quantity to support both their cameras and Olympus'.
